The photochromic glass is a photochromic glass obtained by adding silver halide to glass or adding a photosensitive compound of molybdenum and tungsten to the glass and the organic interlayer. When the photochromic glass is exposed to the sun or other light, its color will gradually darken as the light increases. After the irradiation is stopped, it can automatically return to the original color. The coloration and fading of the glass are reversible and durable, and can achieve the effect of automatically adjusting the indoor light. Photochromic glass is mainly used for buildings that require glare avoidance and that require automatic adjustment of light intensity.
